EFARBUY 94-Piece 9.48mm Valve Shim Kit – For Yamaha YZ/WR 250/400/426/450 & More

This is an open-box valve shim kit from EFARBUY—still new, just the box was opened.

You get 94 shims, all 9.48mm in diameter, with thicknesses ranging from 1.20mm all the way to 3.50mm.

That covers pretty much any adjustment you'd need.

They're made from Cr12MoV steel, so they're tough and wear-resistant.

This kit is primarily for Yamaha dirt bikes: YZ250F, YZ450F, WR250F, WR450F, YZ426F.

But it also fits other bikes like the Suzuki RMZ450, Suzuki Hayabusa GSX1300R, and Yamaha V-Max 1700.

Basically, if your engine uses 9.48mm OD shims, this kit probably covers it.

Comes with a 1-year warranty.

Great for DIY valve adjustments—buy once and have every size on hand.
